Robertshaw 5225-047 Limit Control

The Robertshaw 5225-047 is a heavy-duty LCH series manual reset limit control designed for critical over-temperature protection in commercial cooking and HVACR applications. Engineered as a fixed high limit switch, this component features a factory-calibrated trip point at 450°F (232°C) to ensure system safety by interrupting the power circuit upon reaching the thermal ceiling. The assembly includes a 24-inch capillary and a 3/16" x 7-5/8" nickel-plated copper bulb, providing superior corrosion resistance and thermal sensitivity in demanding kitchen environments.

This SPST break-on-rise control is built with a negative biased power element diaphragm, specifically designed to fail-safe by opening the circuit if the capillary loses pressure integrity. Rated for 30 Amps at 125-480V AC, the manual reset limit thermostat is a standard replacement for Henny Penny equipment (#16738) and other high-capacity fryers or appliances requiring a "trip-free" safety mechanism. Its M2 switch type ensures the control cannot be bypassed or reset while the reset button is actively depressed, maintaining a strict safety boundary for field installations.

• Corrosion Resistance: Features a nickel-plated copper bulb and capillary to withstand harsh caustic environments and high-heat cycles.
• Fail-Safe Engineering: Designed with a negative-biased diaphragm that triggers a safety shutdown if the sensing element is damaged.
• High Electrical Capacity: Robust 30A SPST switch handles high-voltage loads up to 480V AC without the need for additional contactors in many configurations.
• Trip-Free Reset: The manual reset mechanism prevents the unit from maintaining an "on" state if the reset button is held down during an over-temp condition.

• What is the reset type for the Robertshaw 5225-047? This is a manual reset (M2) control, meaning the technician must physically press the button to restore the circuit after a 450°F trip occurs.
• Can the 450°F temperature setpoint be adjusted? No, this part is a fixed temperature limit, factory-calibrated for precision and to prevent unauthorized field tampering with safety settings.
• Is this control compatible with 24V systems? Yes, while rated for high voltage, it is also approved for 35 VA pilot duty at 24V AC applications.
